使用nicstat查看网卡状态

我以前用脚本实现对实时网卡流量统

Xml代码

#!/bin/bash

NAME=nic_flow

PIDFILE=/var/tmp/$NAME.pid

LOGFILE=/var/tmp/$NAME.log

function start(){

if [ -f "$PIDFILE" ]; then

echo $PIDFILE

exit 2

for (( ; ; ));do

eth=$1

[ -z "${eth:-}" ] && eth=eth0

time_range=$2

[ -z "${time_range:-}" ] && time_range=1

ifconfig | awk '{print $1}' | grep "eth" > /dev/null

[ $? -gt 0 ] && echo "wrong NIC device" && exit 10

RX_1=$(cat /proc/net/dev | grep "$eth" | awk -F'[ |:]+' '{print $4}')

TX_1=$(cat /proc/net/dev | grep "$eth" | awk '{print $9}')

sleep $time_range

RX_2=$(cat /proc/net/dev | grep "$eth" | awk -F'[ |:]+' '{print $4}')

TX_2=$(cat /proc/net/dev | grep "$eth" | awk '{print $9}')

clear

echo -e "`date +%k:%M:%S` RX TX" | tee -a $LOGFILE

RX=$((${RX_2}-${RX_1}))

TX=$((${TX_2}-${TX_1}))

if [[ $RX -lt 1024 ]];then

RX="${RX}B/s"

elif [[ $RX -gt 1048576 ]];then

RX=$(echo $RX | awk '{print $1/1048576 "MB/s"}')

else

RX=$(echo $RX | awk '{print $1/1024 "KB/s"}')

if [[ $TX -lt 1024 ]];then

TX="${TX}B/s"

elif [[ $TX -gt 1048576 ]];then

TX=$(echo $TX | awk '{print $1/1048576 "MB/s"}')

else

TX=$(echo $TX | awk '{print $1/1024 "KB/s"}')

echo -e " $eth $RX $TX " | tee -a $LOGFILE

done&

echo $! > $PIDFILE

}

function stop(){

[ -f $PIDFILE ] && kill `cat $PIDFILE` && rm -rf $PIDFILE

}

case "$1" in

start)

start $2 $3

;;

stop)

stop

;;

echo $"Usage:$0 {start|stop,NIC device(eth*), time_range(s)}"

exit 2

esac

今天发现一个更好用的工具nicstat。

nicstat可以提供更加全面的网卡信息。

显示TCP流量统计

显示UDP流量统计

报告进出网卡的字节数

报告进出网卡的数据数

报告网卡利用率

报告NIC饱和度和其他信息

安装make环境

yum install gcc gcc-c++ make automake autoconf -y

由于nicstat依赖32 bit glibc package，所以

yum install libgcc.i686 glibc.i686 glibc-devel.i686 -y

下载文件并安装

cd /usr/local/src

wget http://nchc.dl.sourceforge.net/project/nicstat/nicstat-1.92.tar.gz

tar xf nicstat-1.92.tar.gz

cd nicstat-1.92

cp Makefile.Linux Makefile

make

安装脚本：

#/bin/bash

#blog

SOFT_DIR=/usr/local/src

function nicstat_ins {

echo "===========will inst nicstat"

ping -c 1 -t 1 www.baidu.com

if [[ $? -gt 0 ]];then

echo "nameserver 8.8.8.8\rnameserver 202.96.128.68" >> /etc/resolv.conf

yum install gcc gcc-c++ make automake autoconf -y

yum install libgcc.i686 glibc.i686 glibc-devel.i686 -y

cd $SOFT_DIR

wget http://nchc.dl.sourceforge.net/project/nicstat/nicstat-1.92.tar.gz

tar xf nicstat-1.92.tar.gz

cd nicstat-1.92

cp Makefile.Linux Makefile

make

[ $? -eq 0 ] || error "\033[31m there are something to make \033[0m"

echo "alias nicstat='bash $SOFT_DIR/nicstat-1.92/nicstat.sh'" > /etc/profile.d/nicstat.sh
